“…Currently, vibration and noise problems are becoming increasingly prominent, and the application of damping materials is one of the most direct and effective methods for reducing vibration and noise [ 1 ]. Nitrile butadiene rubber (NBR) has excellent mechanical strength, damping properties, promising oil and heat resistance, and is widely used in damping materials [ 2 , 3 ]. However, due to the influence of the glass transition temperature ( T g ), the single-component NBR’s high damping temperature range is lower than room temperature, and the effective damping temperature range is generally narrow and cannot necessarily meet the needs of different engineering fields and application environments [ 4 , 5 ].…”

To enhance the damping properties of nitrile butadiene rubber (NBR), the elastomer used was blended with chlorinated paraffin 52 (CP52) to prepare NBR/CP52 composites. The results showed that CP52 could significantly enhance the damping properties of NBR and shift the glass transition temperature (Tg) to lower temperatures. Molecular dynamics models of the CP52/NBR system were established, and the damping properties of the CP52-reinforced NBR were investigated using molecular dynamics (MD) simulations. Through the combination of MD simulations and the experimental results, the essential mechanism of the enhanced damping properties of the NBR was methodically expatiated and was ascribed to the Cl-CP-H····NC-NBR (type I) and CP-Cl····H-NBR-CN (type II) analogous hydrogen bonds formed between NBR and CP52. The higher the CP52 content, the higher the analogous hydrogen bond concentration, and the better the damping properties of the CP52/NBR composites. The experimental results were very consistent with the MD simulation results, meaning that the combination method can provide a new means to optimize the design of damping materials and broaden the application range of small polar molecules in the damping modification of polar rubber materials.

“…Polyvinyl chloride (PVC) is an amorphous polymer with excellent properties such as acid–base corrosion resistance, flame retardance, and aging resistance. [ 1–3 ] Due to the strong polar chlorine atom (Cl) on the side chain, PVC has poor‐machining performance and is easily decomposed (the decomposition temperature is lower than the melting temperature). [ 4 ] Therefore, many plasticizers and heat stabilizers must be added to the processing to improve PVC processing performance.…”

Modifying nanoparticles for polymer nanocomposites is important for multifunctional and low-cost developmental direction. However, nanoparticles have several deficiencies, such as dispersion, agglomeration, and poor binding ability with most polymers. This work used soft polyvinyl chloride (PVC with 33.1% plasticizer volume) as the matrix. Polycaprolactone (PCL) was synthesized on the surface of SiO 2 by the bridging effect of silane coupling agent (SiO 2 -PCL), which was expected to improve the bond strength between SiO 2 and soft PVC matrix. Moreover, it enhanced the dispersion of SiO 2 in the PVC matrix. The results revealed that SiO 2 -PCL was nanodispersed in a soft PVC matrix and played a plasticizer role in the composite, which enhanced the tensile strength and elongation at break of PVC composites. The thermal stability and solvent extraction stability of PVC composites elevated with the increase of SiO 2 -PCL content. When the content of SiO 2 -PCL was 8 wt%, the tensile strength (14.54 MPa) and elongation at break (149.47%) of PVC composites were the highest, 64.36% and 60.48% higher than those of unfilled PVC, respectively. It was indicated that PVC composites were dramatically toughened and strengthened by modified SiO 2 , improving their overall performance.

“…The most used strategy to improve the wear phenomenon, from the point of view of the development of new materials, is the study of nanostructure reinforcement. Nanoclays, carbon nanotubes, and graphene are currently very studied as reinforcing additives in elastomeric materials [16][17][18]. The most critical factors in improving rubber composite properties by nanostructures are nanofiller distribution and compatibility with the rubber matrix.…”

Organoclay nanoparticles (Cloisite® C10A, Cloisite® C15) and their combination with carbon black (N330) were studied as fillers in chloroprene/natural/butadiene rubber blends to prepare nanocomposites. The effect of filler type and load on the physical mechanical properties of nanocomposites was determined and correlated with its structure, compatibility and cure properties using Fourier Transformed Infrared (FT-IR), X-ray Diffraction (XRD), Thermogravimetric Analysis (TGA) and rheometric analysis. Physical mechanical properties were improved by organoclays at 5–7 phr. Nanocomposites with organoclays exhibited a remarkable increase up to 46% in abrasion resistance. The improvement in properties was attributed to good organoclay dispersion in the rubber matrix and to the compatibility between them and the chloroprene rubber. Carbon black at a 40 phr load was not the optimal concentration to interact with organoclays. The present study confirmed that organoclays can be a reinforcing filler for high performance applications in rubber nanocomposites.
